4 Claims.

This invention relates to new and useful improvements in multiplepouring devices for ingot molds, and it is among the objects thereof toprovide apparatus for simultaneously pouring regulable multiple streamsof molten metal to a plurality of ingot molds.

Another object of the invention is the provision of a multiple pouringdevice which shall be movable with reference to rows of ingot molds intoi two or more of which the molten metal is poured simultaneously, andwhich shall be provided with manual controls for regulating the volumeof the flow streams to the several molds into which the metal issimultaneously poured.

5 Still another object of the invention is to provide multiple pouringdevices with mechanically operated tilting and tipping mechanism forcontrolling multiple fiow streams and in which the flow controlmechanism is adapted to provide speedy and positive adjustments of thevolume of the several flow streams.

A further object of the invention is the provision of means whereby themultiple pouring de-- vice is adapted to the pouring of large or small 5ingots in molds having different center distances.

These and other objects of the invention will become more apparent froma consideration of the accompanying drawings constituting a part hereofin which like reference characters designate like parts and in which:

55 With reference to Figs, 1 to 3 inclusive of the drawings, thestructure therein illustrated consists of a concrete base I providedwith a pit for receiving ingot molds 2, the pit having shoulders 3. Thebase I is provided with tracks 4 upon which a steel frame, constructedof channels and. plates 5 is mounted on wheels 6 that ride on the railsto render the sub-structure of the pouring device movable. A cross-framel is supported on the wheel frames 5 and a ball-joint 8 is mounted inthe cross-frame I. A pair of longitudinally spaced flow troughs 9 arerigidly mounted on the frame, a feeding orifice i0 being provided at thebottom of the flow troughs. There are two troughs 8 to which metal issupplied through the orifice ll of a single pouring ladle E2, the viewof Fig. 3 being a plan view of onehalf of the pouring device. The ladleI2 is provided with brackets i3, Fig. 3, having spherical seats thatrest upon dumbbell-shaped bearings M, Fig. 1, one end of which issupported on levers l5, which are pivoted at l6, Fig. 3, and connectedto cranks i1. 5

The front end of the ladle i2 is provided with a spherical shapedbearing bracket l8 that rests upon the spherical ball-joint 8. Levers I5are connected to the cranks I! by a link l9 and the cranks H areconnected by shafts through reduction gears 2i and a worm and worm gear22 are driven by a motor 23. the gear being housed in a metal box whichmay be referred to and designated as a transmission 24.

Motor 23 is controlled by a switch or lever 25 and the wheel axles 6 aredriven by a motor 26 controlled by a lever 21, the traversing motor 26being provided with a brake 26a that is operated by a foot pedal 21a.

A plurality of contact brushes 28 are mounted on cross-arm support 29,attached to the frame structure to make contact with rails 30, supplyingcurrent for the motors 23 and 26.

Referring to Fig. 1, metal issupplied to the pouring ladle 12 from aladle 3| which receives the molten metal from a melting furnace, ladle3| being provided with a pouring orifice 32 having the usual stopper forcontrolling the flow.

As shown in Fig. 2, the parts, with the exception of the traversingmotor and its controls, are duplicated, there being two flow openings IIand Ila for the pouring ladle [2 into stationary flow spouts 9 and 9a.

The operation of the apparatus shown in Figs. 1 to 3 inclusive isbriefly as follows: with the pouring ladle I! in its normal position, asshown in cross-section, in Fig. 1 of the drawings, it rests upon thefront central ball-joint 8 and the two horizontally spaceddumbbell-joints II. One of the dumbbellsjoints II is permanently fixedin the end of lever I5 and the other fits into a socket in lever I51:and into the bracket I3 to provide for misalignment in moving the ladle.The metal is caused to flow from the main ladle 3| through the spout 32into the pouring ladle I2 with the ingot molds 2 lined up below thestationary flow spouts 9 and 9a. The operator manipulates control levers25 and 25a which energize the motors 23, which, in turn, actuate cranksI1 and I1a which, through links I9, pull the bell crank levers I5forward. Movement of levers I5 raise the pouring receptacle I2, causingit to tilt about its front central ball-joint 8 and molten metal willflow from the openings II and Ma. The flow from the openings I I and IIa is regulated by tipping the pouring receptacle I2 about its centralball-joint 8 and joints I4, this being accomplished by the controls 25and 25a to raise the lever I5 or I5a as the case may be. In Fig. 3,which is a half plan view of the device, the line :c:r denotes one ofthe tipping axes, while the tilting axis occurs at a longitudinal linethrough the center of the ball-joint 8, such line being at right anglesto the center line, shown in the drawings as running through theball-joint 8.

By means of the controls 25 and 25a, the pouring receptacle I2, is inthe first instance, tilted to raise the rear portion thereof to regulatethe volume of flow to the stationary spouts 9 and by furthermanipulation of the individual controls 25 and 25a, the receptacle maybe tipped to obtain independent regulation of the flow through each ofthe flow openings II and Na of the pouring receptacle.

By means of the hereinabove described apparatus, a plurality of ingotmolds can be poured simultaneously with positive control of the flowstream from the pouring receptacle. The pouring receptacle I2 is of suchcapacity that the pouring of the metal from the ladle 3| may progress ata rate independently of the rate the metal is poured into the ingotmolds, since the control of the flow from the pouring receptacle I2 tothe ingot molds through the flow spouts 9 may be regulated independentlyof the flow from the supply This continuous pouring eliminates thenecessity for stopping-oil. the flow from the main ladle which sometimescauses freezing or sticking of the stopper plug, and at the same timethe independent regulation of flow to the ingot molds permits slowpouring of the metal to the molds which is advantageous in that iteliminates splashing in the mold and is productive of uniformly denseand sound ingots. The pouring to multiple molds simultaneously permitsslowing of the pouring to any desired degree which allows control orregulation of the individual streams. When a pair of ingot molds havebeen fully teemed, the controllers 25 and 25a are manipulated to reversethe motors 23 and 23a. which causes the pouring receptacle I2 to tiltback to the position where the level of the molten metal is below theflow openings II and Na, thus shutting off the flow. The traversingmotor 26 is then energized and the entire receptacle moves on tracks 4to position where the stationary flow spouts 9 will be centered above anempty pair of ingot molds, and the pouring operation is then repeated.

The apparatus shown and described in connection with Figs. 1 to 3 of thedrawings is especially adapted for use in pouring small ingots such asalloy steel, but for use' in the multiple pouring of ingots with largercenters such as seven ft. ingots for sheet metal fabrication, it wouldnecessitate lowering one end of the pouring receptacle an excessiveamount in the tipping operations, and for this reason, the form ofmultiple pouring apparatus shown in Figs. 4 to 7 inclusive of thedrawings, is preferred. This structure is slightly modified, althoughinherently it embodies the same principles of pouring controls describedin connection with Figs. 1 to 3 of the drawings.

The structure of Figs. 4 to 'I inclusive is as follows: The numeral l0Idesignates the ladle by which the molten metal is supplied to thepouring device; I02 the pouring receptacle which, instead of having acentral front bearing support, is provided with longitudinally spacedbearings I03 and I03a at the front bottom portion of the receptacle,these bearings being mounted on levers I04 which are pivoted to across-frame I05 at I06. The pouring receptacle I02 is open at the top sothat in either its normal upright or tilted position the opening will bein alignment with the discharge opening IOIa of the ladle, thuspermitting continuous pouring from the ladle when the multiple pouringdevice is in use. The pouring receptacle I02 is supported at its rearportion by roller I01 that is mounted on a bell-crank I08 which issupported on a bearing I09. One end of the bellcrank I08 is connected bya link I I0 to a crank I I I that is rotated through a transmission I I2driven by motor H3. Levers I04 are connected by links IIS and Se tolevers IIS and IIBa mounted on a rock shaft II1 which is provided with alever II8 that is connected by a link I I9 to the transmission I20. Uponrotation of the rock shaft H1 in one direction, link II5 will be pulleddownwardly to tip one end of the pouring receptacle I02 and in thereverse direction of movement of the rock shaft, link II5a will be drawndownwardly to tip the receptacle in the opposite direction. The tippingmechanism is actuated through a transmission I20 driven by motor I2I,while the tilting operation is by the transmission H2 and motor II3 aspreviously explained.

The rear roller support I01 for the tilting receptacle is mounted on abracket I01a which is carried by shaft I09 that in turn is actuated bythe bell-crank I08. The pouring receptacle is mounted on a framestructure that is supported by wheeled axles I22 on rails I23 of thesubstructure. Ingot molds I24 are supported on wheeled trucks I25 placedbeneath the receptacle which is adapted to traverse the row of ingotmolds for the pouring operations.

A stationary flow spout I26 is provided beneath the flow passages I21and I21a of the pouring receptacle I 02. Reference numerals yy and y'y',Fig. 5, designate the tipping axes of the pouring receptacle. NumeralI21 designates the controller and numeral I2I the tipping motor, I28 thecontroller for the traversing motor, not shown; and I29 the controllerfor the tilting motor H3.

The space designated by the numeral I30 is for the main ladle stopperoperator. The operation of the structure shown in Figs. 4 to '7inclusive of the drawings is briefly as follows:

With the pouring ladle in the position shown in Fig. 4 and a pluralityof ingot molds lined up beneath the stationary spouts I26 and I26a, thetilting motor H3 is energized by the controller I29 which, throughoperating mechanism II2, III, IIO, I09, I08 and MM, causes rollersupport I01 to raise the rear portion of the pouring receptacle I02,thereby tilting it on the fulcrum supports I03 and I03a. When it isdesirable or necessary to tip the receptacle I02, about either axes w ory'y, the controller I21 is manipulated to energize the tipping motor l2lin either direction of rotation, depending upon which axes, yy or y'y',the tilting receptacle is thereby tipped around.

In this manner, the metal flowing from the passages I21 and I210. of thepouring receptacle can be separately controlled to regulate the flow ofthe metal to the ingot molds. When the molds are filled, the tiltingdevice is operated to lower the pouring receptacle by shutting on theflow irom passages I21 and l2'la to theflow spouts I26 and l28a. Thepouring receptacle is then moved by manipulating controller I28 of thetraversing motor to bring the flow spouts to center with an empty pairof ingot molds.

Fig. 6 of the drawings illustrates the use of the device when pouringlarge ingots and Fig. 7 for small ingots, the spacing of the ingotsbeing such that a pair can be aligned with the flow spouts by centeringthe latter with the ingot molds.

The invention may also be employed to control the flow of metal forquadruple pouring by providing a plurality of openings in the flowspouts which are rendered movable to tip them as shown in Fig. 9 of thedrawings. Apparatus for this purpose, with reference to Figs. 8 to 10inclusive of the drawings, consists of a supply ladle having an opening202 above a pouring receptacle 203 which, as in the structure of Fig. 4,is provided with a pair of ball supports 204 and 20% longitudinallyspaced at the front of the receptacle and a supporting roller 205 at therear of the receptacle, the roller for tilting and the movableball-joints for tipping being operative through the same mechanismdescribed in con nection with Fig. 4.

The tilting roller 205 is mounted on an arm 206 carried by shaft 201that is rocked by a lever 208 operated by a crank 209 of a transmission2i0 that is driven by a motor 2H. The front ball supports 204 and 204aare mounted on levers 2I2, operated by cranks 2I3, carried by a rockshaft 2M which is operated by a crank 2i5 of a transmission 2 l6 drivenby a motor 2, the latter being designated the tipping motor. Links 2 IBe have slotted openings 2l8 which engage pins 2l9 of the rock arm, andin one direction of rotation of rock shaft 2, the lever 2i2 will beactuated in the opposite direction of movement and the rock shaft lever2i2a will be actuated to raise or lower the ball-seat 204 or 204a,respectively, thus tipping the pouring receptacle 203 in I the mannerdesired to control the flow of the metal from the passage 220 or 220a toa pair of movable now spouts 22! and 22 la, each of which is providedwith a pair of flow passages, the spouts 22! having passages 223 and223a.

The flow spouts 22l are suspended by links 224, supported on levers 225.pivoted at 226, having link connections 22'! with a rock arm 228,mounted on rock shaft 229, having a crank 230 connected by link 23l to acrank 232 of a trans.- mission 233 driven by motor 234, there being aseparate actuating mechanism for each of the movable flow spouts asshown in Fig. 10 of the drawings. The numeral 235 designates the troughtipping controller; numeral 236 the ladle tipping controller; 231 theladle tilting controller; 238 the trough tipping controller; and 239 thecontroller for the traversing motor, not shown. The numeral 240designates the ingot mold supported on wheel trucks 2.

The operation of the above described mechanism is briefly as follows:Metal is poured from ladle 20l to the pouring receptacle 203, and thelatter is tilted by manipulation of controller 231, which energizesmotor 2 and raises the rear supporting roller 205, through thetransmission 2) and connecting linkage. The pouring receptacle is thentipped to regulate the flow through passages 220 and 220a bymanipulating the controller 236 to energize motor 2 to actuate levers2I2 and 2l2a, through the transmission 2"; and the rock shaft 2, thetipping being around the axes 11y and y'y', this being the same controland operating mechanism as shown in Fig. 4, excepting that the leversare connected to the rear of the apparatus. As the metal flows to themovable troughs 22l, the volume of flow from the separate flow streams222 and 222a. of trough 221, and 223 and 223a oi trough 22in. can beregulated by the trough tipping controllers 235 and 238 which energizemotors 234a and 234, respectively, which, through transmission 233a and233, operate links 23 la and 23 I, through which levers 225a and 225 areactuated. As the levers are moved, the troughs are tilted as shown inFig. 9, the illustrations being greatly exaggerated for this purpose.

By this manner of control, the flow of metal from the pouring receptacle2l3 through the pair of flow passages to the troughs can be regulated asdesired, and the multiple streams flowing .from each of the tiltingtroughs can be regulated as desired to simultaneously pour the metalinto four ingot molds.

When the trough is perfectly level, it is supported on four supportingtrunnions, which consist of brackets with a round end. ()nto these roundbracket ends a socket on the trough rests. When the trough is tipped, itis supported by levers 225 or 225a with the opposite ends of the troughsupported by the brackets and trunnions. This gives the trough athree-point suspension, rigid enough so that it will not turn over,which would happen if it was supported on the levers 225 and 225a only.

It will be apparent from the foregoing description of the invention thatmultiple pouring apparatus constructed and operated in accordancetherewith provides positive means for obtaining regulable multiplestreams of molten metal for charging or pouring a plurality of ingotmolds simultaneously. It is also apparent that the apparatus is ofrugged, compact and relatively simple mechanical construction in whichthe operating parts are subjected to minimum wear.

Although several embodiments of the invention have been hereinillustrated and described, it will be apparent to those skilled in theart that various modifications may be made in the details ofconstruction without departing from the principles herein set forth.
